Good old covid, well my son had it and it so transpired that my s7 stayed with his dad, whilst s5 (had covid) and stayed at home with me. It wasnt very nice not to have s7 at home for 5 days in a row, but once he was back home, we were back to normal schedule. We are going away for over 2 weeks shortly, it doesnt mean that H gets to have the boys for longer before or after. I personally think if it interferes with what you already have planned its a simple no, you stick to your schedule.
